Gemmie a sec and I'll post some pics of mine

Whoops... I misread his case! He has a PC71. I have a 68. Oh well. It's the same dimensions side to side so IMHO it'll work.
Ok I've built two water cool systems and BOTH have used 1991 Ford Ranger heater cores. They're perfect. They have good, usable dimentions, and are 5/8 in and 5/8 out. Which is jsut perfect for 1/2 inch lines. <g>
Now I had two of these on hand when I started this current project.
Heater Core
Ok! So here's the heater core.
(everything in the background is R/C plane building supplies, a set of plans still tacked down on the work bench<g>)
Where's it's going to go. Note the power supply is in the computer to make sure it will fit. Also the found round holes drilled in the side. I decided that the best way to secure the heater core once installed was a large set of zipties in the front and back that hold the radiator taught up against the chassie.
Now the radiator didn't quite fit. Actually it fit EXTREAMLY snug, but it fit. UNTIL I pushed the bottom(of the radiator) over the indention where the slots for the drive bay screws go. So... How do we resolve this???
The hammer in the above pic was used to "crunch" in both sides of the radiator. The sides of the heater core do not contain fluid so they CAN BE bent in very carefully. THIS TAKES VERY LITTLE PRESSURE to bend in the sides. Watch down through the heater core(between the fins) do NOT come CLOSE to moving or bumping the "viens" that run down the inside of the core. That's where the coolant will run throguh and you don't want a leak.
ALSO!!! It is important to note that the entire top and bottom metal pieces CAN NOT be bent. YOU WILL LEAK!!! I lost the first radiator to that(ouch $15 from autozone, luckly my roommate form college works at one and ganked me one<grin> Mad props Sgt. Eddy Slaughter!)
Now that we've gotten the radiator to fit over the drive bay indention we're good to go!
Final Product
I hope that I helped in any way and thinking about it I know that I havn't as that radiator is too long to stand up above the space in between you PSU and the space left above it =( oh well you can try the top blowhole like me and add another PSU for fun
or susped the pump there
